Abstract
Abstract An apparatus for providing contact between a liquid and solid particles having an upright vessel with an upper outlet and a pair of lower outlets, a plurality of concentric upwardly directed inlets into said vessel with one of the outer inlets including a means for swirling its discharge around the inner inlet, means for axially adjusting the discharge position of the central inlet and means for directing oversized particles to one of said lower outlets and smaller particles to the other of said lower outlets. Such apparatus is particularly useful in providing intimate contact between solid salts and an acid, such as salt such as sodium chloride, to produce a volatile acid and sulfate granules.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
An apparatus for providing intimate contact between a liquid and a solid, comprising an upright vessel having an upper outlet and a lower outlet, and terminating in an upwardly facing spray nozzle adapted to spray liquid into said vessel, means defining a first annular chamber surrounding said liquid inlet, said first annular chamber connecting into said vessel and facing upwardly and opening into said vessel at substantially the same level as said spray nozzle, a tangential inlet into said first annular chamber to cause solids to be discharged therefrom in swirling relationship to said liquid inlet spray nozzle and to be fluidized within said vessel, means defining a second annular chamber surrounding said first annular chamber for introducing gas into said vessel in surrounding relationship to said first annular chamber, said second annular chamber facing upwardly and terminating at substantially the same level as said spray nozzle and said first annular chamber.
Claim 2
Independent Claim
152 words
An apparatus for providing intimate contact between a liquid and a solid, comprising an upright vessel having an upper outlet and a lower outlet, and terminating in an upwardly facing spray nozzle adapted to spray liquid into said vessel, means defining a first annular chamber surrounding said liquid inlet, said first annular chamber connecting into said vessel and facing upwardly and opening into said vessel at substantially the same level as said spray nozzle, a tangential inlet into said first annular chamber to cause solids to be discharged therefrom in swirling relationship to said liquid inlet spray nozzle and to be fluidized within said vessel, means defining a second annular chamber surrounding said first annular chamber for introducing gas into said vessel in surrounding relationship to said first annular chamber, said second annular chamber facing upwardly and terminating at substantially the same level as said spray nozzle and said first annular chamber.
Claim 3
Dependent Claim
38 words
An apparatus according to claim 1, wherein said lower outlet of said vessel includes a product outlet, an oversized particle outlet, and a sizing grate covering said product outlet to divert oversized particles to said oversized particle outlet.
Claim 4
Dependent Claim
24 words
An apparatus according to claim 1, including means for adjusting the position of said spray nozzle axially with respect to said fluidized solid inlet.
Claim 5
Dependent Claim
27 words
An apparatus according to claim 1, including means connected to said upper outlet for separating solid particles from gas discharged from the upper portion of said vessel.
Claim 6
Dependent Claim
24 words
An apparatus according to claim 1, including means in the open ends of said annular chambers to increase the velocity of fluids exiting therefrom.
Claim 7
Independent Claim
136 words
An apparatus for producing sulfate granules and a volatile acid gas from a salt and sulfuric acid, comprising a reactor vessel having an upper gas outlet and a lower granule outlet, a liquid inlet extending vertically into said vessel and terminating in a spray nozzle adapted to spray liquid upwardly into said vessel, a fluidized solid inlet into said vessel being positioned in surrounding relationship to said liquid inlet and adapted to discharge fluidized solids upwardly in surrounding relationship to said liquid inlet spray nozzle, said fluidized solid inlet terminating at substantially the same level as of said sPray nozzle, and a hot gas inlet into said vessel adapted to introduce gas upwardly in surrounding relationship to said liquid inlet spray nozzle, said hot gas inlet terminating at substantially the same level as said spray nozzle.
Claim 8
Independent Claim
136 words
An apparatus for producing sulfate granules and a volatile acid gas from a salt and sulfuric acid, comprising a reactor vessel having an upper gas outlet and a lower granule outlet, a liquid inlet extending vertically into said vessel and terminating in a spray nozzle adapted to spray liquid upwardly into said vessel, a fluidized solid inlet into said vessel being positioned in surrounding relationship to said liquid inlet and adapted to discharge fluidized solids upwardly in surrounding relationship to said liquid inlet spray nozzle, said fluidized solid inlet terminating at substantially the same level as of said sPray nozzle, and a hot gas inlet into said vessel adapted to introduce gas upwardly in surrounding relationship to said liquid inlet spray nozzle, said hot gas inlet terminating at substantially the same level as said spray nozzle.
Claim 9
Dependent Claim
33 words
An apparatus according to claim 6, wherein said third inlet includes a plurality of tubes extending in general parallel relationship to said liquid inlet and being spaced radially outward from said liquid inlet.
